SRX345 Use Case

Branch Office Secure SD-WAN & Next-Gen Firewall Consolidation

A global retailer with 75 small branches deploys SRX345-JSB hardware (requires SRX345-JSB or JSE) equipped with 16GE (8x SFP), 4 GB RAM, 8 GB Flash, 4x MPIM slots, internal power supply, cable and RMK. The device terminates dual-MPLS and fiber links, enforces SSL inspection and IPS, and integrates SD-WAN path steering under a single pane. Outcome: 40% TCO reduction through consolidated routing, firewalling and WAN optimization, 35% faster failover, and centralized policy orchestration for consistent branch security.

Data Center Microsegmentation & East-West Traffic Security

An e-commerce data center creates isolated VLAN zones for web, application, and database tiers using SRX345-JSE hardware (requires SRX345-JSB or JSE), 16GE (8x SFP), 4 GB RAM, 8 GB Flash, 4x MPIM slots, internal power, cable and RMK. Acting as an east-west firewall, it inspects inter-VLAN flows with AppID and threat intelligence. Outcome: 80% reduction in lateral attack surface, policy-driven isolation of critical workloads, and 2 Gbps sustained throughput with full threat prevention, ensuring compliance with PCI DSS and GDPR.

Managed Services Multi-Tenant VPN Aggregation & Centralized Management

A service provider scales secure connectivity for 120 SMB clients by deploying SRX345-JSE chassis (requires SRX345-JSB or JSE) featuring 16GE (8x SFP), 4 GB RAM, 8 GB Flash, 4x MPIM slots, internal PSU, cable and RMK. Each tenant receives dedicated VRF, IPsec VPN termination and bandwidth policing. The platform supports J-Web and REST APIs for template-based provisioning. Outcome: 60% faster customer on-boarding, granular per-tenant SLAs, and 99.99% uptime SLAs with fully segmented management domains.
